A new species of soldier beetle (family Cantharidae) from Eocene Baltic amber: Malthodes (s. str.) vallombrosa sp. nov., is described, diagnosed and illustrated. The morphological affinities with the most similar species are discussed. The Eocene Baltic amber was very rich in species of the genus Malthodes. The evolution of these insects probably began after or near the mass extinction that occurred 66 Ma.

This study is based on oribatid mites of the subfamily Arcoppiinae (Oribatida, Oppiidae) collected from rainforest litter in Izabal Department, Guatemala. A new species of Arcoppia—A. tetraramosa sp. nov.—is described. In having several long, barbed branches of the bothridial seta and comparatively long dorsal notogastral setae, the new species is similar to A. dechambrierorum and A. serrulata, but can be distinguished from both by the morphology of the rostrum, the length of dorsal notogastral setae, the sculpturing of basal part of the prodorsum, the length of the costula, and the presence of the specific ridge-like structure in front of the transcostula. A supplementary description of Wallworkoppia cervifer is presented and its main morphological traits are summarized.

The life cycle and larval diet of Amphipsyche meridiana Ulmer 1902 were investigated in a natural freshwater habitat at Kasetsart University's Kamphaeng Saen Campus in Nakhon Pathom Province, Thailand. Larvae were collected monthly from December 2021 to November 2022. Most species of Hydropsychidae have five larval instars. The first to fifth larval instars were found in the stream throughout the year. Head capsule widths of the first to fifth instar larvae were 0.1–0.3, 0.4–0.6, 0.7–0.9, 1.0–1.2, and 1.3–1.6 millimeters, respectively. The highest number of larvae was found in July 2022. Adult emergence occurred throughout the year, with the highest number occurring in April 2022. A. meridiana's life cycle was characterized as multivoltine, with year-round recruitment. The Canonical Correspondence Analysis (CCA) was used to determine how conditions in the environment influenced larval abundance. The factors influencing the amounts of larvae are water depth, water temperature, pH, dissolved oxygen, ammonia-nitrogen, and sulfate. The larvae of this species are omnivorous filterers. The main food types found in the gut were blue-green algae and green algae, comprising 34.11% and 33.07% of its ingestion. In addition, the digestive tract was abundant with diatoms, rotifers, and insect fragments, accounting for 32.82% of the diet.
研究人员在泰国那空巴吞府格萨沙大学Kamphaeng Saen校区的天然淡水栖息地调查了Amphipsyche meridiana Ulmer 1902的生命周期和幼虫食性。从 2021 年 12 月到 2022 年 11 月,每月收集一次幼虫。大多数绣线菊科物种都有五个幼虫龄期。溪流中全年都能发现第一至第五龄幼虫。第一至第五龄幼虫的头囊宽度分别为 0.1-0.3、0.4-0.6、0.7-0.9、1.0-1.2 和 1.3-1.6 毫米。幼虫数量最多的年份是 2022 年 7 月。成虫全年都有出现,其中以 2022 年 4 月出现的数量最多。A.meridiana的生命周期特点是多伏期,全年都有新成员。采用典型对应分析法(CCA)确定环境条件对幼虫数量的影响。影响幼虫数量的因素包括水深、水温、pH 值、溶解氧、氨氮和硫酸盐。该物种的幼虫是杂食性滤食者。肠道中发现的主要食物类型是蓝绿藻和绿藻,分别占其摄食量的 34.11% 和 33.07%。此外,消化道中还有大量硅藻、轮虫和昆虫碎屑,占食物的 32.82%。

A new fossil leafy liverwort species is described based on its inclusion in Eocene Rovno amber. This species has morphology that is characteristic of extant representatives of the families Frullaniaceae and Jubulaceae, i.e., conduplicate-trilobed leaves with a ventral lobule forming a saccate-clavate watersac with its mouth directed towards the base of the stem, larger dorsal lobes and deeply bifid underleaves. The leaf lobes in the studied plant seem to be dentate near the apex, a character state together with the shape of the underleaves and the underleaf insertion, connects the new species with the Jubulaceae, particularly the extant genera Jubula and Neohattoria, rather than with the Frullaniaceae. The minute size of the fossilized plant, as well as the shape and size of the ventral lobules is reminiscent of Neohattoria, but the more distant lobule position and presence of terminal gynoecia with a single floral series of bracts having entire margins better fit species of Jubula. The fossil is therefore better placed in Jubula, as J. polessica sp. nov., based on its overall morphological similarity with extant members of that genus.
根据始新世罗夫诺琥珀中的叶状肝草化石,描述了一个新的叶状肝草物种。该物种的形态特征与现存的葫芦科(Frullaniaceae)和茱布科(Jubulaceae)的代表物种相同,即对折三叶叶片,腹侧小叶形成囊状棍棒状水囊,其口朝向茎基部,背侧叶片较大,叶下深二裂。所研究植物的叶裂片在近先端处似乎有齿,这一特征连同叶下的形状和叶下的插入,将该新种与爵床科,尤其是现存的爵床属和新爵床属联系在一起,而不是与弗氏爵床科联系在一起。化石植株的微小尺寸以及腹裂片的形状和大小让人联想到 Neohattoria,但其较远的裂片位置和顶生雌蕊群的存在以及苞片全缘的单花系列更适合 Jubula 的物种。因此,根据其与现存 Jubula 属成员的整体形态相似性,该化石更适合归入 Jubula 属,即 J. polessica sp.

Gregarines (Apicomplexa: Eugregarinida) are protists that live in the digestive tract and other body cavities of numerous terrestrial and aquatic invertebrates. The gregarine fauna of Eastern Europe has not yet been sufficiently studied. In the course of this study, we aimed to record gregarines living in the insides of the most widespread species of darkling beetles (Tenebrionidae: Coleoptera) in steppe zone of Ukraine. We found 7 species of gregarines belonging to 3 families: Actinocephalidae, Gregarinidae and Stylocephalidae, with the latter family being the most diverse. Gregarina Steinina diaperis was recorded in Diaperis boleti, Gregarina ormierei in Gonocephalum pusillum, and G. ovoidea in Asida lutosa. As for members of the family Stylocephalidae, Sphaerorhynchus cf. hamoni was found in G. pusillum, Stylocephalus gigas in Blaps lethifera, S. longicollis in Gnaptor spinimanus, and S. oblongatus in A. lutosa, Opatrum sabulosum, Oodescelis melas, and Pimelia subglobosa. G. ovoidea Wellmer, 1911, S. gigas Filipponi, 1949, S. longicollis (Stein, 1848) Watson, 1916 and S. oblongatus (Hammerschmidt, 1838) Watson, 1916 were first found in a new host species. All the identified species are new to the fauna of Ukraine and are recorded for the first time in the steppe zone of Eastern Europe.
革囊虫(Apicomplexa: Eugregarinida)是生活在许多陆生和水生无脊椎动物消化道和其他体腔中的原生动物。东欧的藻类动物群尚未得到充分研究。在这项研究中,我们的目标是记录生活在乌克兰草原地区最常见的暗色甲虫(Tenebrionidae:鞘翅目)体内的garines。我们发现了隶属于 3 个科的 7 个种类:其中后一科的种类最多。在 Diaperis boleti 中记录到了 Steinina diaperis,在 Gonocephalum pusillum 中记录到了 Gregarina ormierei,在 Asida lutosa 中记录到了 G. ovoidea。至于 Stylocephalidae 科的成员,在 Gonocephalum pusillum 中发现了 Sphaerorhynchus cf. hamoni,在 Blaps lethifera 中发现了 Stylocephalus gigas,在 Gnaptor spinimanus 中发现了 S. longicollis,在 A. lutosa、Opatrum sabulosum、Oodescelis melas 和 Pimelia subglobosa 中发现了 S. oblongatus。G. ovoidea Wellmer, 1911, S. gigas Filipponi, 1949, S. longicollis (Stein, 1848) Watson, 1916 和 S. oblongatus (Hammerschmidt, 1838) Watson, 1916 是首次在新的寄主物种中发现。所有已确定的物种都是乌克兰动物区系中的新物种,也是首次在东欧草原区记录到这些物种。

The Afrotropical lappet moth genus Hypotrabala Holland, 1893 is reviewed utilising specimens housed in the African Natural History Research Trust collections. The synthesis of morphological and DNA analyses has reconciled discrepancies in previous treatments of the genus and Hypotrabala is clearly delimited with implications on the nomenclature and taxonomy. The genus Epitrabala Hering, 1932 syn. n. is synonymised with Hypotrabala resulting in the following changes: Hypotrabala argenteoguttata (Aurivillius, 1909) comb. rev. is revived, H. horridula Tams, 1925 stat. rev. is removed from synonymy with Epitrabala nyassana (Aurivillius, 1909) and two taxa, H. horridula seydeli Tams, 1925 syn. n. and Epitrabala argyrostigma Hering, 1932 syn. n. are synonymised with it. Epitrabala nyassana is transferred to the genus Leptometa (comb. n.) as is Leptometa sanguicincta comb. n. (previously assigned to Hypotrabala), while Hypotrabala odonestioides Berio, 1937 is excluded from Hypotrabala although its generic placement remains uncertain. Based on the structures of the male eighth sternite, Hypotrabala fontainei stat. n. is raised to species status and a new genus Megatrabala gen. n. is described for the striking taxon M. regalis (Tams, 1953) comb. n. Furthermore, 19 new species are described: H. aurantiaca, H. cinereamargo, H. exquisita, H. extenuata, H. giustii, H. indefinita, H. igneata, H. lunda, H. lydiae, H. magnimacula, H. obscura, H. ophioglossa, H. pallens, H. pruinosa, H. retorta, H. smithi, H. tabithae, H. tamsi and H. volynkini spp. n. Certain incongruencies between the results of the barcode analyses and species concepts in this genus and Lasiocampidae more generally are discussed.
本研究利用非洲自然历史研究信托基金收藏的标本,对非洲热带羽扇蛾属 Hypotrabala Holland, 1893 进行了综述。形态学和 DNA 分析的综合结果调和了以前对该属处理中的差异,明确划分了 Hypotrabala 的范围,并对命名法和分类法产生了影响。Epitrabala Hering, 1932 syn. n.属与 Hypotrabala 属同名,导致以下变化:Hypotrabala argenteoguttata (Aurivillius, 1909) comb. rev. 被恢复,H. horridula Tams, 1925 stat. rev. 被从与 Epitrabala nyassana (Aurivillius, 1909) 的同义中删除,两个分类群 H. horridula seydeli Tams, 1925 syn.n. )和 Leptometa sanguicincta comb.此外,还描述了 19 个新种:H. aurantiaca、H. cinereamargo、H. exquisita、H. extenuata、H. giustii、H. indefinita、H. igneata、H. lunda、H. lydiae、H. magnimacula、H. obscura、H. ophioglossa、H. pallens、H. pruinosa、H. retorta、H.n. 讨论了条形码分析结果与该属和 Lasiocampidae 的物种概念之间的某些不一致之处。
